Input Voltage(VIN): 3-16V(20V max) Digital I/O Pins: 54 (of which 15 provide PWM output) Analog Inputs: 16 I/O FLASH: 256 KB (of which 4 KB is used by the bootloader) SRAM: 8KB EEPROM: 4KB Frequency: 16MHz
如下图: arduino板子上基本端口如图描述,对几个比较特殊的端口下面详细说明下:VIN端口:VIN是input voltage的缩写,表示有外部电源时的输入端口。如果不使用USB供电时,外接电源可以通过此引脚提供电压。(如电池供电,电池正极接VIN端口,负极接GND端口)AREF:Reference voltage for the analog inputs(模拟输入的基准电压)...
...Unlike the low-side MOSFET, which has the drain -source voltage clamped by its body diode during turn off..., the high-side MOSFET turns off with a VDS of approximately VIN- VOUT, plus the spike across it...注意: 开关管分别断开,关闭时候,电流的流向。 Buck电路的占空比:D=Vo/Vi。
其他型号:如 Mega 2560 有更多 PWM 引脚,需查阅具体板卡文档。 2. 如何使用 PWM 使用analogWrite(pin, value) 函数: pin:PWM 引脚编号(如 9)。 value:占空比,范围 0(0%)到 255(100%)。 示例: analogWrite(9, 128); // 引脚9输出50%占空比(128/255 ≈ 50%) 3. PWM 原理 占空比(Duty Cycle):...
I measured the voltage at A4 in respect to gnd, and with a 12.46 Vin, I got a 3.52 Vout. I also reported the actual ADC output of the analogRead by printing avgVal to the LCD, and got 778 out of a max of 1023 (0-1024). ...
If you need hardware serial for both then, yes, you need an Arduino such as the Mega which has more than one hardware serial. When I develop new projects for myself I use hardware serial to talk to the BT module and a usb-serial adapter and software serial to talk to the serial moni...
